RRA model sinks into ground

[Aya Alwan]

Hello,

I'm using Opensim 4.5 to run RRA and CMC on a walking trial. The model sinks into the ground as if GRF data don't exist. I'm attaching the GRF, IK, and model files. I use the default actuators, constraints, and tasks files from gait2354 model. Could you help resolve the issue? I tried the recommendations from previous posts and it still falls into the ground. I would highly appreciate it if someone could check my GRF file.

Thank you,

Aya
